方案
我在片段内部(图像视图和视频视图)或(像Surfaceview一样自定义,在左边和右边的照片内部),我需要输出片段布局作为视频,加入将照片和视频合并为一个视频。
问题
我真的不知道如何做这项工作,也许是为了记录屏幕而不是专业。也许你可以帮帮我?一些教程,想法或任何东西都会很好。
感谢。

虽然this不适用于片段,但它会对您有所帮助。您可以通过5.0 API使用OpenGLES纹理制作视频。
或制作屏幕录像机服务。像这样,
public boolean startRecord(MediaProjection mediaProjection, File file) {
mRecorder = new MediaRecorder();
mRecorder.setVideoSource(MediaRecorder.VideoSource.SURFACE);
mRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mRecorder.setAudioSource(MediaRecorder.AudioSource..DEFAULT);
mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
mRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
mRecorder.setOutputFile(file.getPath());
mRecorder.setMaxDuration(60000);
mRecorder.setVideoSize(720,1280);
try {
mRecorder.prepare();
mMediaProjection = mediaProjection;
Surface targetSurface = mRecorder.getSurface();
mDisplay = mMediaProjection.createVirtualDisplay("ScreenRecorder", 720, 1280, 240,
DisplayManager.VIRTUAL_DISPLAY_FLAG_AUTO_MIRROR, targetSurface, null, null);
mRecorder.start();
mRecording = true;
showNotification();
} catch (IOException e) {
e.printStackTrace();
return false;
}
return true;
}
在活动中获取MediaProjection
{
btnStartRecording.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = mMediaProjectionManager.createScreenCaptureIntent();
startActivityForResult(intent, REQUEST_CODE_SCREEN_CAST);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_CODE_SCREEN_CAST) {
if (resultCode != RESULT_OK) {
Toast.makeText(this, "Permission denied, close this app", Toast.LENGTH_SHORT).show();
finish();
}
mMediaProjection = mMediaProjectionManager.getMediaProjection(resultCode, data);
if (mMediaProjection == null) {
return;
}
File moviesFolder = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MOVIES);
File movieFile = new File(moviesFolder, "test.mp4");
if (mService != null) {
mService.startRecord(mMediaProjection, movieFile);
}
else{
mMediaProjection.stop();
}
} else {
super.onActivityResult(requestCode, resultCode, data);
}
}
您可以在显示屏上记录所有内容。
